Kennedy Jr. is revising his ethics agreement to divest his interest in litigation against an HPV vaccine maker and directing the stake to his adult son, The New York Times reported Friday, citing a written response to questions from senators who are weighing his confirmation as Health and Human Services secretary.

RFK Jr has long expressed views that conflict with scientific evidence, especially on vaccines, and his nomination has provoked opposition from public health experts. But he has also adopted positions with popular support, scrutinising the use of food additives and urging that the power of big pharma be curbed.

If confirmed by the Senate, Kennedy would head the Department of Health and Human Services (HHS), which oversees many of the country’s health agencies, from the Food and Drug Administration (FDA) to the Centers for Disease Control and Prevention (CDC).

Senators had objected to the financial conflict posed by Robert F. Kennedy Jr.’s decision to retain a financial stake in lawsuits against a major drug company. It remains unclear whether any proceeds would be redirected.
